Oral composition

Abstract

Provided is a pumping type toothpaste product including a toothpaste composition. The toothpaste composition includes a polishing agent, and thus prevents the piston of a pumping type container from being worn by the polishing agent contained in the toothpaste composition so that the contents of the container may be ejected out smoothly. Also provided is a gel-like toothpaste composition having excellent viscosity retentivity. Further, provided is an oral composition showing high elasticity even at low viscosity, undergoing little change in viscosity with time and having significantly improved shape retentivity, flowability and dispersion stability through the synergic effect of xanthan gum and a thickening polymer.

What is claimed is: 
     
       1. A pump dispenser toothpaste product comprising:
 a pump container having a piston and 
 a toothpaste composition for use with the pump container having a piston; 
 wherein the toothpaste composition comprises sorbitol, a liquid polyol, and a precipitated silica as polishing agent; 
 wherein the sorbitol is present in an amount of 0.001-20 wt % based on the total weight of the toothpaste composition, 
 wherein liquid polyol comprises any one selected from the group consisting of polyethylene glycol (PEG) 200-600, glycerol, propylene glycol, ethylene glycol, polypropylene glycol and a mixture thereof, 
 wherein the liquid polyol is present in an amount of 10-85 wt % based on the total weight of the toothpaste composition, 
 wherein the precipitated silica is present in an amount of 1-20 wt % based on the total weight of the toothpaste composition, 
 wherein hydroxyl or ether groups of the liquid polyol forms hydrogen bonding with hydroxyl groups of the sorbitol, and the hydroxyl or ether groups of the liquid polyol forming hydrogen bonding have a mole number at least 0.2 times of a mole number of the hydroxyl groups of the sorbitol, 
 wherein the pump container having piston comprise a dip pump, and 
 wherein the toothpaste composition has a change in viscosity of 100 to 15,000 cP after least 2 years as compared to the viscosity of the composition upon its preparation, when viscosity measurement is carried out under conditions of 25° C., 20 rpm and 5 cycle by using BrookField, RVT spindle No. 7. 
 
     
     
       2. The pump dispenser toothpaste product according to  claim 1 , wherein the liquid polyol is present in an amount of 40-75 wt % based on the total weight of the toothpaste composition. 
     
     
       3. The pump dispenser toothpaste product according to  claim 1 , wherein the toothpaste composition further comprises any one selected from the group consisting of sodium fluoride, sodium monofluorophosphate, tin fluoride, ammine fluoride and a mixture thereof. 
     
     
       4. The pump dispenser toothpaste product according to  claim 1 , wherein the toothpaste composition further comprises a bubbling agent,
 wherein the bubbling agent is a laurylsulfonate. 
 
     
     
       5. The pump dispenser toothpaste product according to  claim 1 , wherein the bubbling agent is present in an amount of 0.5-5 wt % based on the total weight of the toothpaste composition. 
     
     
       6. The pump dispenser toothpaste product according to  claim 1 , wherein the toothpaste composition has a viscosity of 5,000-36,000 cP under conditions of 25° C., BrookField, RV-7, 20 rpm. 
     
     
       7. The pump dispenser toothpaste product according to  claim 1 , wherein the toothpaste composition has a viscosity of 5,000-20,000 cP under conditions of 25° C., Brookfield, RV-7, 20 rpm.
